pingqiuandClaude Opus 4.6 80be2ec05a feat: CP13-5 — reconnect handshake + WAL catch-up on SetReplicaAddrs ...

Bug: SetReplicaAddrs created fresh shippers (hasFlushedProgress=false),
so after disconnect, the new shipper used bootstrap instead of reconnect
handshake. Bootstrap doesn't replay missed WAL entries — barrier hung.

Fix:
- blockvol.go: SetReplicaAddrs checks if old shipper group had durable
  progress (AnyHasFlushedProgress). If so, seeds new shippers with
  hasFlushedProgress=true → they use reconnect handshake + catch-up.
- shipper_group.go: add AnyHasFlushedProgress() helper.

3 baseline FAILs now PASS:
- ReconnectUsesHandshakeNotBootstrap: reconnect path used, not bootstrap
- CatchupMultipleDisconnects: repeated disconnect/reconnect recovers
- CatchupDoesNotOverwriteNewerData: catch-up completes, safety exercised

7 tests promoted to CP13-5 primary proof.
TestAdversarial_NeedsRebuildBlocksAllPaths still FAIL (CP13-7 scope).
